IMPROVEMENTVJI'N" GRAlN- SEPARATORS.

Specification forming part of Letters Patent No. 173,259, dated February8, 1876; application filed- July 19, 1875.

' State of Ohio, have invented certain new and useful Improvements inFanning-Mills; and

, do hereby declare that the following is a full,

clear, and exact description thereof, reference being had to theaccompanying drawings, and to the letters of reference marked thereon,

.making a part of this specification.

My invention relates to fanning-mills 'or grain-separators; and itconsists in the construction of the shoe containing the sieves,

.and in the devices for shaking said shoe, as

will be hereinafter more fully set forth.

, In order to enable others skilled in the art to .which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in whichFigure 1 is an end elevation of a fanning mill embodying my invention.Fig. 2 is a longitudinal vertical section of the same.

A represents the frame of a fanning-mill, with hopper B and fan (3, thelatter being rotated by any suitable mechanism attached to the mill. Drepresents the shoe, suspended upon, or by, spring-straps a a. 1n thelower part of the shoe D are arranged four screens or sieves, E E, ofunequal length and fineness. The bottom sieve is the shortest andfinest, the second one is longer and coarser, and so on in regulargradation; and under the front end ofeachsieve is a spout, G, whichspouts are arranged to run two to each side of the shoe. At the lowerend of the shoe is another spout or outlet, G], for carrying offeverything that does not pass through the first sieve.

By this arrangement of sieves and spouts any kind of grain may be passedthrough the machine and properly cleaned and separated. One end of thefan-shaft b is provided with a crank, d, which is connected by a rod, I,with an arm, J, projecting at right angles from a rod or shaft, 6, whichhas its bearings at the end of the frame A below the upper end of theshoe. From the rod or shaft 6 projects an arm, h, which is bound withrubber i or other suitable material, to prevent noise, and extends upinto a slot, .90, made in a block, L, attached to the under side of theshoe D at the front orv upper end. By the rocking of the shaft 6 the armh operating in the slotted block causes the shoe to move or shakeendwise; but as the slot min the block is made wider than the thicknessof the arm placed therein, it will be seen that the shoe is acted uponwith a blow at each vibration of the shaft, thus obtaining exactly thesame knocking motion as-a sieve operated by hand.

Having thus fully described my invention, what I claim as new, LettersPatent, is-

The combination, with the suspended shoe D, of the block L, having slotas, and the rocking-arm h having binding z, and projecting into theslot, the parts being arranged to give the shoe a knocking motion,substantially as herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this15th day of July, 1875.
